not bothered about the router, it will be in modem mode anyway. I am coming from a flawless 220mb connection so I dont want to lower it any more than I have to. It might be BT I end up going with anyway despite their [censored] customer service because it will work out cheaper overall.
No ISP other than virginmedia use modem mode. It is not an option. Unless you have a new router you likely will find the WiFi better on most ISP supplied devices now.
I argue VM have Modem Mode as their routers are that bad, everytime I have used VM I have had to use modem mode. With other ISPs I have zero issues using the supplied kit. My BT SmartHub I never turned it off. The Sky Q router I have now has 1000+ hours uptime all the time. My TalkTalk router was getting 60+ days uptime.
The only bad talktalk router is the HG633. Users often get it swapped for a DLink 3782 which is fine.
RE BT CS, it's not too bad nowadays, it's got a fair bit better especially since BT promised in late 2016 to handle 80% of calls in the UK.
If you have any major issues, there are good escalation channels.
There are options for you if you insist on using your own device, e.g. buy a VDSL2+ modem router or a bt openreach modem on ebay e.g. hg612 (but the openreach modems are now a bit long in the tooth as they were phased out a few years back now with all in one devices by ISPs so you're getting old tech).
My advice, see how you get on with the ISP kit, it works for 99% of users, myself included and I have 30+ devices hooked up. Make sure to split the 2.4 and 5ghz bands from day one. My BT SmartHub actually had better WiFi than a Netgear Nighthawk which I ended up sticking back in the cupboard as it wasn't getting to the back bedroom.
I would rule out AAISP as in my experience 2 hours of 4K on Netflix is around 11-15Gb.
EDIT: Having used BT based services and virginmedia, I would opt for a BT based one everytime. My Sky, TalkTalk and BT has been worlds better than virginmedia was, VM I had a lot of jitter, single thread slowdowns every evening, higher pings.
